REVERSIBLE WINDOW-SASH- Specification of Letters Patent.

Patented Dec. 18, 1906.

To all whom it may concern.-

Be it known that I, JEFFERSON GRANT RoBBE, a citizen of the UnitedStates, residing at Canon City, in the county of Fremont and State ofColorado, have invented new and useful Improvements in ReversibleWindow-Sashes, of which the following is a specification.

This invention relates to windows, and has for its object to produce acomparatively simpleEinexpensive device of this character in which thewindow-sections may be moved upward and downward, as usual, in thewindow-casing and readily turned to a horizontal or any desired angularposition or completely reversed and one wherein the window when inclosed position will be practically air-tight and dust-proof.

A further object of the invention is to provide a simple and effectivemechanism for moving the weather-strips within the casing into and outof engagement with the window-sash for maintaining the window in itsclosed position or permitting of its sections being turned upon theirpivotal axes, as heretofore mentioned.

To these ends the invention comprises the novel features of constructionand combination of parts more fully hereinafter described.

In the accompanying drawings, Figure 1 is a fi'ont perspective view of awindow and its casing embodying the invention and disclosing thewindow-sections turned to partially open position. Fig. 2 is a frontperspective view of one of the stiles, showing the sash-guides andweather-strips arranged therein. Fig. 3 is a rear perspective View ofthe same and illustrating the mechanism for operating theweather-strips. tail view, partly in section, of a portion of one of thestiles and window-sashes and showing the sash as pivotally engaged withthe hanger. Fig. 5 is a section taken on the line 5 5 of Fig. 4 andshowing the sashes arranged in juxtaposition. Fig. 6 is a similar viewtaken on the line 6 6 of Fig. 3. Fig. 7 is a perspective view of one ofthe hangers. Fig. 8 1s a perspective view of one of the cam membersemployed in the strip-operating mechanism. Fig. 9 is a perspective viewof the channel-iron included in the strip-operating mechanism. Fig. 10is a detail view of one of the sashes.

Fig. 4 is a de- Referring to the drawings, 1 designates a window casingor frame comprising vertical side stiles 2, an upper rail 3, and a sill4, the rail and sill being provided with fixed projecting weather-strips5 for a purpose which will later appear.

Each of the vertical stiles 2 is provided, as illustrated in Fig. 2,with a pair of spaced vertical guideways or grooves 6, each havingarranged for travel therein a hanger block or member 7, fixed to one endof and operated by a cable or other appropriate flexible element 8,arranged for travel over a guide-pulley 9 and having attached to itsother end a weight (not shown) arranged for travel as usual within awell or recess provided in the casing 1. The hanger-blocks 7 arepreferably of the form illustrated in Fig. 7, having a central solidportion in which is formed a threaded opening 10, while at the upper endof the block there is formed an extended portion 11, having a centraltooth 12 and marginal teeth 13, arranged at opposite points upon theside edges of the extension 11. It may here be mentioned that when thisform of block is employed it is attached to the cable 8 by pressing theend of the latter onto the central tooth 12 and bending or folding thelateral teeth 13 downward thereover, or if a chain be used instead ofthe cable, one link of the chain may be engaged with the tooth 12 andthe teeth 13 folded into engagement with the chain. By this means theblock is securely attached to the weighted element, but may be readilydetached when circumstances require. Each of the stiles 2 is furtherprovided with a pair of appropriately-spaced longitudinal grooves orrecesses 14., designed to receive movable weatherstrips 15, which extendlongitudinally of the stile throughout its entire length and are eachprovided adjacent its upper and lower ends with pins or members 16,which project rearwardly therefrom through the stile and have their rearends threaded. The pins on one strip are in horizontal alinement withthose on the other, whereby these pins are arranged in pairs, vand eachpair of pins receive upon their rear ends a substantially T-shaped cammember 17, the horizontal portion or head of which is slotted at itsopposite ends, as at 18, for the reception of the threaded ends of thepins 16, to which the Inn;

member 17 is secured by means of inner and outer nuts 19 19,respectively, while the vertical portion or stem 20 of each member isdisposed at an inward angle or inclination relative to the plane of theadjacent face of the stile 2 and provided with a longitudinal slot 21,which receives and in which moves a fastening pin or key 22, fixed toand extending transversely through suitable openings 22 in alongitudinally-reciprocatory actuating member 23, preferably in the formof an angle-plate fixed for sliding movement upon the inner or rear faceof the stile 2 by means of screws or other fastening devices 24, engaging longitudinal slots 25, formed in the plate, the stile beingmortised at points 25 coincident with the slots 25 for the reception ofthe slotted arms or stems 20, as and for the purpose hereinafterexplained.

The plate 23, the side flanges 23 of which seat in and are guided bysuitable kerfs formed in the casing 1, has these flanges cut away at asuitable point, as at 26, to register with a corresponding mortise 27,formed in the casing at the rear face of the stile 2, and in thismortise is seated an operating member or lever 28, having a longitudinalslot 29, de-

signed to receive a screw or otherfastening device 30, by which thelever is attached to the plate 23, the slot 29 being also adapted toreceive a projecting pintle 31, formed on a plate 32, attached by screwsor otherwise to the inner face of the stile 2, whereby the lever ispivoted and is also susceptible of longitudinal movement, thuspermitting of its being drawn outward for operation or moved to anormally-unobstructing position.

Each side of the sash-frame 33 has formed therethrough a series ofopenings 34, arranged, respectively, adjacent to the longitudinal centerand ends of the sash, these perforations being designed for thereception of a pivoting pintle or axle 35, which has its inner endtapped into the threaded opening 10 within the hanger or guide-block 7and ordinarily engaged through the central opening 34 of the sash, thuscentrally pivoting the latter. When, however, the windowopening isbarred or screened upon its outer side, the pivoting-pins 35 maybeextended through either the upper or lower openings 34 to permit of thesash swinging on its axis without interfering with the bars or screen.

At the upper and lower ends of the sashframes 33 are formed grooves orkerfs 36 to receive the weather-strips 5, while the side bars of thesash-frames are provided with longitudinal kerfs 37 to receive theweatherstrips 15.

In practice when the window is in closed position the strips 15 willseat within the kerfs 37 and serve to'maintain the windowsectionsvertically within the window-opening and guide said sections duringvertical opening and closing movements within the casing and, as usual,this movement of the window section being effected owing to travel ofthe blocks 7 within the guide 6 under the influence of the weightedcords orelements 8. When, however, it is desired to swing thewindow-sections on their pivots, as indicated in Fig. 1, for adjustingthem to a horizontal or angular position or for completely reversingthem, the lever 28 is first drawn outward and its outer end presseddownward, thereby moving the strip 23 vertically upward and causing thepins 22 thereof to travel upwardly and outwardly in the slots 21,thereby forcing the cam member 17 rearwardly relative to the stiles 2and drawing the weather-strips 15 into their reats 14 and flush with theadjacent outer faces of the stiles 2, whereupon the window sections orsashes may be readily rotated on their pivots 35. After the sashes areagain returned to closed position the outer end of the lever is lifted,thereby moving the strip 23 downward and causing the pins 22 to act inthe slots 21 for drawing the members 17 inward and moving the strips 1.5outward into the recesses 37.

It is to be particularly observed that under my improved constructionthe window-sec.- tions can be turned to a horizontal position and insuch position raised. to the top of or lowered to the bottom of thewindow-casing to thus wholly open the latter and obtain increasedventilation or that the windows may be moved to any desired positionfacilitating cleaning or reversed when needful during the latteroperation.

From the foregoing it is apparent that I produce a comparatively simpleeflicient device admirably adapted for the attainment of the ends inview, it being understood that minor changes in the details herein setforth may be resorted to without departing from the spirit of theinvention.

Having thus fully described the invention, what is claimed as new is 1.In a device of the class described, a win (low-casing, movableweather-strips carried thereby, said strips being coextensive in lengthwith the height of the casing, a sashframe pivotally mounted within thecasing and having seats for the reception of the weather-strips, a cammember connected with the weather-strips and having a cam way, areciprocatory member operable independently of the movements of the sashand having a fixed portion engaging the way, and manually-operated meansfor reciprocating the member to actuate the cam member for retractingthe weather-strip.
